Abstract

The utility model provides a cutter special for thin-wall discs, and relates to the field of cutting of thin-wall discs. The cutter special for the thin-wall discs is exquisite in structure, simple in use, good in use effect and short in machining cycle. The cutter special for the thin-wall discs comprises a blocky first cutter body and a blocky second cutter body. The two ends of the first cutter body are the first head end and the first root end respectively, the two ends of the second cutter body are the second head end and the second root end respectively, the first root end and the second root end are integrated, a gap is formed between the first head end and the second head end, and the gap is gradually enlarged from outside to inside. A first cutting inlet and a first cutter opening are formed at the two ends of the top edge, facing the gap, of the first head end respectively, a second cutting inlet and a second cutter opening are formed at the two ends of the top edge, facing the gap, of the second head end respectively, the first cutter opening and the second cutter opening are symmetric, and the distance between the first cutting inlet and the second cutting inlet is larger than the distance between the first cutter opening and the second cutter opening. The cutter special for the thin-wall discs has the advantages of being convenient to use and low in rejection rate.

Description

The special cutter of disk of thin wall

Technical field

The utility model relates to the cutting field of disk of thin wall, relates in particular to the improvement for the accurately machined special cutter of disk of thin wall.

Background technology

At present, thin-wall circular disc type work is many as shown in Fig. 5-6, and some disk of thin wall that are parallel to each other are connected as a single entity by a mandrel, and it first completes roughing adding man-hour conventionally between adjacent discs, more one by one the both ends of the surface of single disk is carried out respectively to fine finishining.Like this, make it have that positioning difficulty is large, difficulty of processing is large, processing effect is poor, high (respectively both ends of the surface processing of lead aircraft percent defective process time, to make it can partially cause single disk to be scrapped, and then cause its integral body to be scrapped because crossed by force direction when fine finishining) etc. defect.

Utility model content

The utility model is for above problem, a kind of delicate structure has been proposed, use simple, result of use is good and the special cutter of the disk of thin wall that the process-cycle is short.

The technical solution of the utility model is: comprise block cutter hub one and block cutter hub two, the two ends of described cutter hub one are respectively head end one and butt one, the two ends of described cutter hub two are respectively head end two and butt two, described butt one and butt two are connected as a single entity, between described head end one and head end two, leave gap, described gap ecto-entad progressively increases progressively;

Described head end one is respectively entry one and the edge of a knife one towards the two ends of the top margin in described gap, described head end two is respectively entry two and the edge of a knife two towards the two ends of the top margin in described gap, the described edge of a knife one and the edge of a knife two are symmetrical arranged and the spacing of entry one and entry two is greater than the spacing of the edge of a knife one and the edge of a knife two.

It is the arc of 30-60 ° that the described edge of a knife one is central angle, and it is the arc of 30-60 ° that the described edge of a knife two is central angle.

It is the arc of 10-30 ° that described entry one is central angle, and it is the arc of 10-30 ° that described entry two is central angle.

The spacing of described entry one and entry two be the described edge of a knife one with the 1.5-3 of the spacing of the edge of a knife two doubly.

When the utility model is used, can directly the two ends of mandrel be positioned on lathe, then open lathe and make its rotation; After completing the roughing in early stage, directly the gap of the cutting knife in this case is aimed at and treated accurately machined disk, and along the radial feed cutting knife of mandrel, make disk enter cutting knife between entry one and entry two, and complete cutting between the edge of a knife one and the edge of a knife two, until the end face of head end one and head end two is fed to the surface of mandrel; Thereby complete simply, efficiently the fine finishining of single disk.

In said process, due to the spacing of the edge of a knife one and the edge of a knife two wall thickness of disk of thin wall (can complete before use the polishing of cutting knife) very, therefore, after primary feed, can complete fine finishining, have the advantages that the process-cycle is extremely short, processing effect is good; Therefore meanwhile, during due to cutting knife feeding, will complete the cutting of disk of thin wall both ends of the surface simultaneously, also effectively avoided the problem of scrapping because of the disk that single load bearing causes, there is feature easy to use, percent defective is low.

The specific embodiment

The utility model is as shown in Fig. 1-6, comprise block cutter hub 1 and block cutter hub 22, the two ends of described cutter hub 1 are respectively head end 1 and butt 1, the two ends of described cutter hub 22 are respectively head end 2 21 and butt 2 22, described butt 1 and butt 2 22 are connected as a single entity, between described head end 1 and head end 2 21, leave gap, described gap ecto-entad progressively increases progressively;

Described head end 1 is respectively entry 1 and the edge of a knife 1 towards the two ends of the top margin in described gap, described head end 2 21 is respectively entry 2 211 and the edge of a knife 2 212 towards the two ends of the top margin in described gap, the described edge of a knife 1 and the edge of a knife 2 212 are symmetrical arranged and the spacing of entry 1 and entry 2 211 is greater than the spacing of the edge of a knife 1 and the edge of a knife 2 212.

Like this, the outside in gap forms cutting position, and the inside in gap has also reserved discharge space to iron filings.

It is the arc of 30-60 ° that the described edge of a knife 1 is central angle, and it is the arc of 30-60 ° that the described edge of a knife 2 212 is central angle.

It is the arc of 10-30 ° that described entry 1 is central angle, and it is the arc of 10-30 ° that described entry 2 211 is central angle.

The spacing of described entry 1 and entry 2 211 be the described edge of a knife 1 with the 1.5-3 of the spacing of the edge of a knife 2 212 doubly.
